Frequently asked questions
Which samples can be analysed using spectroscopy?
In principle, there is a spectroscopic analytical method for almost every conceivable type of sample.
Which spectroscopic methods are available?
There are many spectroscopic methods. Fundamental is the differentiation between atomic spectroscopy (e.g. X-ray spectroscopy), molecular spectroscopy (e.g. microwave spectroscopy, fluorescence spectroscopy), solid state spectroscopy, impedance spectroscopy and laser spectroscopy. FTIR and Raman spectroscopy belong to the area of molecular spectroscopy, like UV/VIS spectroscopy. Energy-dispersive X-ray spectroscopy (EDX analysis) and optical emission spectrometry (OES) can be classed as atomic spectroscopy.
While some of these methods are excellently suited to special analysis tasks or certain substance classes, others are of almost universal application.
With which analytical methods can spectroscopy be combined?
In modern chemistry, spectroscopic methods are not used in isolation. FTIR spectroscopy can be coupled with TGA for the identification and quantification of decomposition products released during the analysis of plastic.
During correlative particle analysis, SEM-EDX analysis as well as FTIR and Raman spectroscopy can be combined with light microscopy for identifying and classifying inorganic and organic particles.
